It is useless, all those limitations are also enforced on the client.

Clients do not download files they already have. Plus, the entity limit was increased last year

Ok, I've found a way to modify the library with IDA, however im unsure if the last instructions that add something needs to be NOP'ed as well.

Went from this:

PHP Code:
E8 52 A4 F4 FF                                  call    _VectorScale
83 C4 10                                        add     esp
10h 

To this:
PHP Code:
90                                                      nop
90                                                      nop
90                                                      nop
90                                                      nop
90                                                      nop
83 C4 10                                                add     esp
10h 
EDIT:
Tested and it works as intended!
